1 tions with relation to said handle.

To this end, the blade-supporting member is pivoted to the handle and in its operative position extends transversely of the handle and while in such position is practically in fixed relation to the handle, and the cap member is also pivoted to the handle and in its operative position overlies the blade-supporting member so as to firmly clamp the blade between them and while in such position is practically in fixed relation to the handle, and

said members are constructed and arranged to be moved into their operative positions by pressure applied to the cap member and to be moved into their inoperative positions by pressure applied to the blade-supporting member.

Provision is made for obtaining a wide separation of thecap member from the bladesupporting member in their inoperative positions.

These and other features of this invention will be pointed out in the claims at the end of this specification.

Fig. 1 is a side elevation of a safety razor and in its operative condition;

Fig. 2, an end elevation of the razor shown in Fig. 1, looking toward the left;

Fig. 3, an end elevation opposite to that 4 shown in Fig. 2;

Fig. 4, a side elevation of the razor shown in Fig. 1 in its fully opened or inoperative position;

Fig. 5, a side elevation of the razor in its Fig. 6, a plan of the razor shown in Fig. 1.

Referring to the drawings, 10 represents the supporting member for the blade 12, and 13 the cap member which co-operates with the supporting member 10 to firmly clamp the blade 12 between them when in their operative position shown in Fig. 1.

The supporting member 10 is designed to rest upon the flat upper end surface 14 of a handle 16 when said member is in its operative position shown in Fig. 1, in which posi-. tion the supporting member extends t'rans versely of the handle 16. The blade-supporting member 10 is pivoted to the handle 16 so as to be moved into an inoperative positionv lengthwise of the handle as shown in Fig. 4'.

In the present instance, the handle 16 is provided at its upper end with a longitudinally extended slot 18, into which is extended a lug or ear 19 on the underside of the blade-supporting member 10, which lug or ear is pivotally secured to the handle by a pivot pin 20. i

The upper end of the handle on one side of the pivot pin 20 is provided with a curved portion 22 having the pivot pin 20 as a center, which enables the supporting member 10 to be turned on the pivot pin 20 into its inoperative position lengthwise of the handle as shown in Fig. 4, and to be turned in the opposite direction into its operative position in Fig. 1 with the bottom of the supporting member 10 engaged with the fiat upper surface 14 of the handle and firmly supported thereby.

The cap member 13 is constructed to overlie the supporting member 10 when the cap member is in its operative position shown in Fig. 1, and to be moved into its inoperative position lengthwise of the handle, and to this end, the cap member 13 is provided at one end with an arm 25 having a substantially short, straight portion 26 and a longer, inclined portion 27, which latter is extended into the slot 18 in the handle 16 and is pivoted to said handle by the pivot pin 28, which is located below and substantially in line with the pivot pin for the blade-supporting member.

The arm is attached to the end of the cap member which is located on the same side of the longitudinal axis of the handle as the curved upper portion 22 of the latter, and as a result bot-h the cap member and the bladesupporting member are turned in the same direction when moved from their operative into their inoperative positions and vice versa.

Both members 10, 13 may be moved from their operative positions shown in Fig. 1 into their inoperative positions, by pressure applied to the underside of the blade-supporting member 10 by the thumb of the hand which grasps the handle.

Both members 10, 13 may be moved from their inoperative positions shown in 4 into their operative positions shown in Fig. 1 by upward pressure applied to the arm 25 of the cap member by means of the thumb of the hand which grasps the handle.

It will thus be seen that the blade-supporting member 10 and the cap member 13 are capable of being simultaneously moved in one direction into their open or inoperative positions, and to be simultaneously moved in the reverse direction into their closed or operative positions, and that these movements may be effected by the thumb of the hand which grasps the handle.

Provision may be made for obtaining a wide opening between the cap member and the blade-supporting member in their in operative positions, and to this end, the handle 16 is provided with recess for the reception of a portion of the arm 25, with the result that in the extreme open position of. the blade-supportin member 10 and of the cap member 13, these members converge from their front toward their rear ends (see Fig. 4) and a wide openingat the front ends of said members is provided for handling the blade 12 to remove it from the member 10 or to place it thereon.

By reference to Fig. 4:, it will be observed that the front or upper end of the blade supporting member 10 projects materially beyond the front or upper end of the cap member 13. and enables the operator to manipulate the blade without danger of cutting the fingers.

In the open or inoperative position of the safety razor as shown in Fig. 4, it will be seen that the rear end of the blade-supporting member 10 rests on the arm 25 of the cap member, so that when the latter is moved upwardly, the arm 25 initially moves the rear end of the blade-supporting member 10 until the cap member 13 has been turned sufficiently to engage its front end with the blade 12 on Fig.

the supporting member 10 (see Fig. 5), and

on further movement of the cap member the blade-supporting member is turned by the front end of the cap member, until the underside of the blade-supportin g member engages the flat upper surface 1% of the handle beyond a plane through the pivot pins 20, 28, in which position the cap member and the blade-supporting member are practically fixed to the handle until positively moved.

When the parts are in the position just described, the flat surface let of the handle, the pivoted lug 22 and the arm 25 have the relation of a toggle with the pin 20 beyond a plane through the pin 28 and the center of the flat surface 14, and the members 10, 13 are thus locked against accidental movement.

The blade-supporting member and the cap member may be suitably constructed to clamp any one of the blades now commonly used and found on the market, but in the present instance, they are shown as adapted to clamp the well-known Gillette blade, and to that end, the supporting member 10 is provided on its upper surface with studs or projections 32 which extend through holes in the Gillette blade, and the cap member 13 is provided with a longitudinal channel 33 for the reception of the studs or projections 32 and which permits the cap member 13 to be moved lengthwise of the blade-supporting member 10 without interference by said studs.

The blade-supporting member 10 is provided on its opposite sides with teeth 35, which form a guard for the blade 12 to prevent the face being cut in the act of shaving.

One embodiment of the invention is herein shown, but it is not desired to limit the in vention to the particular construction shown.

hat is claimed is:

1. In a safety razor, in combination, a handle, a blade-supporting member pivoted to said handle to extend transversely thereof in its operative position and. to move in an arc lengthwise of said member and extend lengthwise of said handle in its inoperative position, and a cap member pivoted to said handle to extend transversely thereof in its operative position and clamp a twoedge blade between it and said supporting member, and to move in an arc in the direction of its length and extend lengthwise of said handle and spaced from said supporting member in its inoperative position to permit the twoedge blade to be removed from between them.

2. In a safety razor, in combination, a handle, a blade-supporting member pivoted to said handle and provided with studs on its upper surface to extend into holes in a bladeplaced on said upper surface, and a cap member pivoted to said handle and co-operating with said supporting member to clamp the blade between them, said cap member having a longitudinal channel into which said studs extend when the cap member and the bladesupporting member are in their positions.

3. In a safety razor, in combination, a handle, a blade-supporting member having on its under surface a lug pivoted to said handle, a cap member provided at one end. with an arm extended under one end of the bladesupporting member and pivoted to said handle, said members extending transversely of the handle in their operative position and being movable into an inoperative position lengthwise of the said handle.

In testimony whereof, I have signed my name to this specification.
